Hemi-Sync® & SAM Tech Research

This paper describes two studies. A first study measured the neural accommodation (changes in ongoing or overall brain-wave activity) associated with complex binaural-beat stimuli. A second study, based on the same protocol, measured changes in ongoing brain-wave activity associated with placebo stimuli.

The Monroe Institute (TMI), through its patented sound technology, has demonstrated changes in focused states of consciousness for thousands of individuals over the last 30 years. While ongoing research at the Institute on the nature of different states of consciousness is yielding rich insights into human development, a continuing challenge for the leadership of TMI is to understand how repeated exposure to Hemi- Sync® technology in controlled workshop environments affects the quality of individual lives.

In 2008 The Monroe Institute began to investigate a complementary method of producing the consciousness altering effects of Hemi-Sync®, a safe and effective essential component of our educational programs for decades. We were looking for an audio support technology that would extend the range, scope and flexibility of our seminar programs and educational materials. The new Spatial Angle Modulation™ (SAM) technology was developed to meet those requirements. SAM will not replace existing Hemi-Sync products or programs, but will hopefully provide the platform for future seminar programs and educational materials.

Gloria, an oncology social worker and a TMI Professional Member, has been offering patients the use of Hemi-Sync® tapes ever since she experienced for herself their health-promoting qualities. The solution to a long-term Hemi-Sync mystery prompted her to write this letter.

The strength and uniqueness of Hemi-Sync is not simply that it employs binaural beats, or even that it uses frequency following response (FFR). Hemi-Sync’s advantage is in the precisely identified wave forms, blended and sequenced over time into specific, complex frequency patterns.

One program in which audioguidance is used is the GATEWAY VOYAGE® conducted at The Monroe Institute® (TMI). Anecdotal reports suggest that peak or similar experiences are a common occurrence during this program, and participants’ lives are often dramatically changed by these events. The unusual frequency and consistency with which such events reportedly occur constitute a phenomenon worthy of investigation. However, to date there have been no systematic attempts to confirm these claims by empirical means.

In response to this question, The Monroe Institute has published quantities of explanatory literature over the years. By now, most people with a lively curiosity about mind-brain technology know many the following.
